The epic Charlie Sheen meltdown of 2011 was so long ago that it's easy to forget just how insane the whole thing got. So here's a quick refresher:
Basically, the Sheenius was the highest paid actor on television until he went all "warlock rock star from Mars," and not only bit, but publicly devoured the hand that fed him.
At one point, Sheen called producer Chuck Lorre a "p*ssy loser," and declared that Two and a Half Men was "doomed" without him.
Lorre responded by killing off Sheen's character, replacing him with Ashton Kutcher, and proving that the inexplicably-popular CBS sitcom would, in fact, be just fine without him.
Bridges don't get any more burned than that and it seemed a safe bet that Sheen and Lorre would never work together again.
